BCM on a 2006

[rsvette182]

Does anyone happen to know if I can switch a BCM from a base 2006 XLR into another base 2006 XLR and expect it to work? Or will it need to be programmed to the car like the radio for example? TIA

I never knew a radio had to be programmed.

That’s what I’ve been told. Apparently it was some sort of anti theft thing GM did to discourage radio thefts, and requires a dealer to program a new one to your car.

Hey

Yes, I do believe the BCM requires programming. I know if you switch to another ECM, reprogramming (marrying) to the VIN is required. A Tech 2 will assist in doing this. Regarding the OEM radio, yes they require marrying to the VIN as well, in order to function. Installing a radio from another car will result in the "Theftlock Activated" message to appear. This is easily resolved using a Tech 2.

XLR radio out of one into another XLR will require a reprogramming with a TECHII or like scanner tool.

BCM will require a reprogram, most likely a dealer. I never could accomplish that task with my TECH II

I was able to confirm that it does indeed need to be programmed to the car, and can be done so relatively easily with a tech 2. Same story with the ecm, tcm, etc.

Hey

It is a bit more involved doing the BCM than the radio ,

In some if not most cases, it takes an online connection to GM along with your TECHII for programming the BCM
